ADJUSTABLE WINDOW-SCREEN.

SPECIFICATION forming part of Letters Patent No. 585,041, dated J une 22, 1897.

Application filed November 12, 1896. Serial No. 611,876. (No model.)

To a/ZZ whom t may concern.-

Be it known that I, EDWIN L. LLOYD, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Adjustable Window- Screens, of which the followingis aspecification.

The object of my invention is to construct a cheap and effective form of adjustable window-screen in which the netting is not obstructed by cross-bars or-other portions of the frame and in which said frame is composed of but few parts, which can be readily manipulated and which are not liable to get out of order.

In the accompanying drawings, Figure l is a perspective view of a window-screen constructed in accordance with my invention, showing the expansion-strip removed from one end of the same. Fig. 2 is a rear view of said expansion-strip. Fig. 3 is a sectional View, on a larger scale, of one corner of the screen, showing the expansion-strip partially projected. Fige is a transverse section on the line at, Fig. 3; andFig. 5 isa transverse section on the line y y, Fig. 3.

The screen comprises the top and bottom bars 1 2 and end bars 3, suitably joined together at the corners, the top bar also having, by` preference, a projecting bead or iiange 4 for closing and hiding the joint between the bottom rail of the sash and the top bar of the screen.

In the under side of the top bar 1 and in the upper side of the bottom bar 2 of the screen is formed a groove or recess 5, these grooves receiving the upper and lower edges of the netting 6 of the screen, the opposite rend portions of this netting being secured by tacks 7 or otherequivalent fastenings to the inner faces of the end bars. 3 of the screen, as shown in Fig. 1.

At each end of the top and bot-tom bars of the screen is a slot 8, extending completely through said bar from top to bottom of the same, and guided in these slots are the expair' sion-strips 9 of the screen, which fit snugly against the face of the netting 6, but are free to slide to and fro over the same.

To a groove 10 in the outer face of each of the expansion-strips 9 is adapted a wire 11, the central portion of which is carried through to the inner face of the strip and forms aprojecting loop 12, which constitutes a handle whereby the strip may be readily manipulated. The end portions of the wire 11 project laterally from the strip, as shown at 13, and have their ends bent upward and backward, so as to form spring-iin gers 14, as shown in Figs. 1, 2, and 3.

The wires 13 are adapted to the grooves 5 of the top and bottom bars of the screen and are free to slide back and forth therein to a limited extent, blocks l5 and 16 being inserted in said grooves for the double purpose of preventing the withdrawal of the upper and lower portions of the netting therefrom and for confining and serving as stops for the wires 13, the spring-iingers 11 bearing against the edges of the blocks 16, so as to constitute frictional retainers for preventing accidental movement ot' the expansion-strips 9 toward each other when the screen has been properly adjusted to the window. The same result might, however, be obtained by contact of the wires 13 with the opposite sides of the grooves 5 in the top and bottombars of the screen.

A window-screen constructed in the manner describedis composed of very few parts, which can be cheaply made and quickly and economically assembled, the netting presenting an unobstructed surface and the eXpansion-strips being exceptionally easy of adjustment.

' Having thus described my invention, I claim and desire to secure by Letters Patent- 1. IThe combination of the top and bottom bars of the screen having grooves for the reception of the upper and lower portions of the netting, and slots at the opposite ends, expansion-strips adapted to said slot-s, and guides projecting from the expansion-strips and entering the grooves of the top and bottom bars7 said guides having portions forming spring retaining-fingers, substantially as specified.

2. The combination of the top and bottom bars of the screen having grooves for the reception of the upper and lower portions of the netting, and slots at the opposite ends, expansion-strips adapted to said slots, fillingblocks in the grooves of the top and bottom strips, and guide-Wires projecting from the expansion-strips into said grooves, and bent so as to forni spring retaining-fingers, substantially as specied.

3. The combination of the expansion-strip of the screen, with a single wire let into a groove in one face of said strip, the central portion of said Wire extending through and projecting from the opposite face of the strip in the form of a loop, and the end portions of the Wire being projected laterally so as to form guides, substantially as specified.

4. The combination of the expansion-strip with a single Wire let into a groove in one face of said strip and having a central portion ED WIN L. LLOYD.
